Process for fixing images by contact heating in a duplicator

摘要

A process for fixing images by contact heating in a duplicator comprising passing a thermoplastic resin powder image formed on a support between at least two heating rollers disposed in proximity to each other; heating the roller as disposed on the image side of the support to a temperature less than the temperature of the roller disposed on the side opposite the image side so that a temperature gradient is produced in the thermoplastic resin powder image to prevent said thermoplastic resin powder image from adhering to the roller disposed on the image side.
